2 Samuel 21:8-14

8But the king took the two sons of Rizpah the daughter of Aiah, whom she bore to Saul, Armoni and Mephibosheth; and the five sons of Michal the daughter of Saul, whom she brought up for Adriel the son of Barzillai the Meholathite:12 9And he delivered them into the hands of the Gibeonites, and they hanged them on the hill before the LORD: and they fell all seven together, and were put to death in the days of harvest, in the first days, in the beginning of barley harvest.

10And Rizpah the daughter of Aiah took sackcloth, and spread it for her upon the rock, from the beginning of harvest until the rain poured on them from heaven, and allowed neither the birds of the air to rest on them by day, nor the beasts of the field by night. 11And it was told David what Rizpah the daughter of Aiah, the concubine of Saul, had done. 12And David went and took the bones of Saul and the bones of Jonathan his son from the men of Jabeshgilead, who had stolen them from the street of Bethshan, where the Philistines had hanged them, when the Philistines had slain Saul in Gilboa: 13And he brought up from there the bones of Saul and the bones of Jonathan his son; and they gathered the bones of them that were hanged. 14And the bones of Saul and Jonathan his son they buried in the country of Benjamin in Zelah, in the sepulchre of Kish his father: and they performed all that the king commanded. And after that God was entreated for the land.
